You can still be asked for an interview or to send details of your current location. There is also a risk of your DTV being rescinded upon approval as others have find out. Some get away with entering Thailand before approval but it's not worth the risk.
Yea DTV is for remote work but outside of Thailand,you can not work for Thai firms or doing Muay Thai, cooking, medical treatment etc. METV is just for tourism and easy to get.
